At Texray, we use Wavelength Dispersive X-ray Fluorescence (WD-XRF). WD-XRF is a non-destructive and highly sensitive instrument we use to analyze elements from Be to U in low ppm concentrations. WD-XRF is used to analyze the chemical composition in both liquids and solids. We can perform qualitative and quantitative analysis with the use of standard and standard-less calibration methods. Our XRF is impressively loaded with a high capacity sample changer and 7 crystals for a wide range of samples and elements.
